Subject: [PATCH 04/13] block: qemu-iotests - add check for multiplication
 overflow in vpc

Message-id: <9e859f3912d1852e48fb7e25a3679bd74500c36d.1438188988.git.jcody@redhat.com>
Patchwork-id: 67198
O-Subject: [RHEL-7.2 qemu-kvm PATCH 3/3] block: qemu-iotests - add check for multiplication overflow in vpc
Bugzilla: 1217349

This checks that VPC is able to successfully fail (without segfault)
on an image file with a max_table_entries that exceeds 0x40000000.

This table entry is within the valid range for VPC (although too large
for this sample image).
